Abstract

A system for controlling handover is disclosed that includes a mobile terminal that enables communications with multiple wireless systems having wireless access stations, and a handover-controlling apparatus that executes control of handover for the mobile terminal, which travels among multiple types of wireless systems. The mobile terminal includes a destination wireless system determining unit that receives downlink signals from the corresponding wireless access stations so as to determine which wireless system accommodates a destination wireless access station based on reception quality of downlink signals. The mobile terminal also includes a destination wireless system reporting unit that sends information indicating the determined wireless system to the handover-controlling apparatus. The handover-controlling apparatus includes a handover-controlling unit that controls handover operations for the mobile terminal based on the information indicating the determined wireless system, which is sent from the destination wireless system reporting unit.
